You're slightly misremembering the GTAIV video. In that he talks about how he has had numerous boyfriends but his romances always fall apart because he's unable to emotionally connect with other people. Also, he is very openly a massive cock slut so I don't doubt that he has been in porn. He goes to a ton of furry conventions and the only reason you go to that shit is to fuck.

So he's just a regular faggot that sucks a dozen dicks every week. Got it.
